LevelUp! Lab for Serverless

Lab Overview And High Level Design

Let's start with the High Level Design.

The diagram below provides a visual representation of the services used in this tutorial and how they are connected. This application uses AWS Amplify, Amazon API Gateway, AWS Lambda, Amazon DynamoDB, and AWS Identity and Access Management (IAM).

As we go through the tutorial, we will discuss the services in detail and point to resources that will help you get up to speed with them.

What Do We Need?

• AWS Amplify : A way to create/host a webpage

• AWS API Gateway : A way to invoke the math functionality

• AWS Lambda : A way to do some math

• AWS DynamoDB : Somewhere to store/return the math result

• AWS IAM : A way to handle permissions.
